BETHLEHEM, Pa. (CBS/AP) — A Pennsylvania university has kicked a sorority off campus due to what officials are calling a “reprehensible” scavenger hunt that involved drugs, alcohol and sexual activity.

Alpha Chi Omega’s Theta Chi chapter lost its recognition by Lehigh University for two years and will be banned from campus through May 2020.

The Lehigh Greek Community blog published by the university says the sorority hosted a December scavenger hunt in which participants were given a list of tasks that involved “the use of drugs and alcohol, sexual activity and other activities” that violate the Bethlehem school’s policy.

The sorority was suspended pending an investigation by a disciplinary committee that called the activity “reprehensible.”

“Lehigh University expects all students to uphold community standards and act in a manner that reflects the university’s Code of Conduct. Violations of these expectations, which are in place to foster a safe, respectful environment for all members of the Lehigh community, will result in consequences,” the university said in a statement.

Eyewitness News also reached out to the sorority’s national office in Indianapolis.

Alpha Chi Omega’s statement reads in part, “The actions of our members in this incident were disturbing and led our leadership to undertake an extensive internal investigation. Following our initial review, we immediately rescinded the membership of nearly one-third of the members of the chapter those women who were most directly involved with this incident.”

Alpha Chi Omega can appeal. The national organization conducted an investigation resulting in probation and individual punishments.
